Flow solvers

Water Lily is a fast three-dimension flow solver written in Julia that can run multi-threaded and on GPUs. Supporting Julia projects include Data-driven and classic Geometric MultiGrid pressure solvers, as well as parametric geometry and flow vizualization routines.

Lily Pad is an interactive two-dimensional viscous flow solver is no longer being developed, but has been used to produce results for top-tier academic journals as well as demonstrate basic flow concept in classrooms and on TV.

Educational notebooks

I use Jupyter notebooks to teach an Introduction to Numerical Python for Engineers (which has an accompanying playlist on youtube), as well as Marine Hydrodynamics and Offshore Engineering Analysis.

Interactive web-apps

I have a set of web apps and Android apps that I use to illustrate fluid dynamic concepts in undergraduate teaching and outreach.
